SPECIFICATION formingpart of Letters Patent 'No. 634,771, dated October 10, 1 899.

Application filed March 28, 1899 To all whom it mag concern:

. Be it known that I, ANNIE DERBY SMITH, of

West Orange, in the countyofEssex andStat'e of New Jersey, have invented a new andjImproved Flour Sifter and Mixer, of which the following is a full, c1ear,and-exact description. The objectof the invention is to provide a new and'improved flour sifter and mixer,

which is simple and durable in construction, arranged to; permit of readily opening up theflour, to thoroughly and uniformly incorporepresented in the accompanying drawings,

forming apart of this specification, in which similar characters of reference indicate corresponding'parts in both the views.

Figure Us a plan view of the improvement, and Fig. 2 is a sectional side elevation of the same on the line 2 2 in Fig. 1.

- The improved flour sieve and mixer is provided with a circular vessel A, having a sieve B for the bottom of suitable mesh and any desired material, and on the top of said vessel is secured a cross-shaped frame 0, having the ends 0' of its bars curved over the annu lar flange A of the vessel A to securely hold the frame in position on the top of the vessel. The frame 0 is provided at its middle with a hub Oi'in which is journaled a vertically-disposed shaft D, provided at its upper end with a suitable crank-arm E, adapted to be taken hold of by the operator-to turn the crank-arm and the said shaft D.

On-the lower endof the shaft D is secured a pressing, mixing, and agitating device for opening up the flour and mixing baking-powder or the like with the flour and for pressing the mixture in a finely-divided state through the meshes or perforations of the sieve B. This device consists, essentially, of a number of bars of wire F, each bent to form two horizontally-extending arms F, spaced a short distance apart, as plainly indicated in Fig. 1-,

Serial No. 710,784. '(llo model.)

and'ex'tending over and'in close proximity to the sieve B, the inner ends F of said arms be in g curved upward to be fastened to the shaft D. The outer ends'of the bars F terminate in a loop F which is curved upward and out- Ward in close proximity to the inner face of I the vessel A, and then upward and inward, and finally downward, to readily cut through the fiourand open it up, to agitate said flour for the purpose described, very little power being required for the operation.

In case there are any small lumps in the flour they are thoroughly broken up either by being thrown over by the bent loops or by being crushed between the arms F and the sieve B, so that all the material is finally forced in a finely-divided state through the meshes of the sieve. h

Having thus fully described my invention, I claim as new and desire to secure by Letters Patent- A flour'sifter and mixer, comprising a circular vessel havinga sieve-bottom, a skeleton frame secured to the top of the vessel by the arms of the frame being bent over the circular rim of the vessel, a shaft mounted to turn in the hub of said frame, a crank-arm on the upper end of said shaft, and a series of mixing and forcing devices secured to said shaft, and each consisting of a piece of'wire bent to form'straight arms extending over the sieve-bottom in close proximity thereto,

the outer ends of the arms terminating in a loop bent upward, inward and downward to form a mixing and agitating device, as set forth. a
